INK DISTRIBUTION FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed April 22, 1914. Serial No. 833,579. 1

for Printing-Presses, of"'which'='the following is a specification.

The principal objects of the invention are the provision of an improvedsystem of ink distribution under which the ink is more uniformly appliedto the cylinder at the points of contact therewith of the form rolls,and the mounting of the form and rider rolls in such manner as to bereadily brought into accessible position for cleaning, adjustmentand thelike.

Other advantageous features of construction and operation will be madeapparent to those skilled in the art from a reading of the subjoineddetailed description taken in connection with the accompanying drawinupon which the description'is predicate and in which. for purposes ofillustration only, is set forth in side elevation a preferred embodimentof the invention.

, In that form of construction chosen as an example the numeral 11designates the plate or form cylinder upon the axle 12 of which isloosely mounted the collar 13 forming an integral part of aframedesignated generally at 14. This frame is in the form of a segment andhas sultably journaled upon its periphery a plurality of trains ofrolls, one train comprising the form rolls 15 and 16 and, the riderrolls 17,' 18 and 19, While the other train comprises form rolls 20, 21and 22 and rider rolls 23, 24, 2'5, and 26. The form rolls of the twotrains are driven from the cylinder gear 27 at a peripheral speedcorresponding to that of the cylinder by means of pinions 28, 29, 30 and3l.suitably geared to the form rolls.

In order to effect a supply of ink in proper degree to both trains ofrolls the final ink drum 32 of the ductor train has mounted upon itsaxis 33 the bearing yoke 34 of a ductor roll 35 which latter is causedin any suitable manner to oscillate upon the axis of the drum with theductor roll and ink drum in continual peripheral contact, the peripheryof the ductor roll contacting alternately with the periphery of thefirst rider rolls 19 and 26 of each of the distributing trainsrespectively wherebythe ink from the drum is supplied independently tothe two trains instead of indirectly to one of the trains through theother, as has been common.

In order to provide for the simultaneous adJustment of the rolls of eachtrain in their relation to the form-cylinder and to throw all of therolls simultaneously out of operative engagement with the said cylinderthe frame 14 is provided with an eccentric 36 suitably mounted upon anaxis 37 and arranged to bear upon the fixed wear block 38. The eccentrichas connected thereto the lever arm 39 which in turn is connected by alink- 40 with a lever 41 fulcrumed at 42. By throwing the lever 41 tothe right the frame together with the trains of rolls are lifted bodilyout of contact with the form cylinder and with the driving pinions outof mesh with the cylinder gear.

In order to bring the distributing train of rolls into a positionreadily'accessible for cleaning, adjustment, or for other purposesprovision is made to rotate the frame and trains of rolls bodily aboutthe cylinder, the frame being provided for this purpose with a segmentrack 43 in mesh with a pinion 44 which latter is adapted to be manuallyrotated by any suitable means, as for instance a crank engaging thesquared end 45 of its shaft. By the rotating of the pinion 4-1 the frameand the trains of rolls will be caused to describe an arc to the right,as viewed in the drawing, s as to bring the rolls clear of the printingpress frame into a position of readv accessibility.
